Hi Nick
Nick Cooper wrote on 2009-10-28 17:29:
Thank you for the quick replies. I thought method 2 must be faster
because it doesn't have to search for variables in the string.
So what is the advantages then of method 1 over 3, do the curly braces
mean anything?
1) $string = foo{$bar};
2) $string = 'foo'.$bar;
3) $string = foo$bar;
I must admit reading method 1 is easier, but writing method 2 is
quicker, is that the only purpose the curly braces serve?
Yes, you're right about that. 10 years ago I went to a seminar were
Rasmus Lerforf was speaking and asked him exactly that question. The
single qoutes are preferred and are way faster because it doesn´t have
to parse the string, only the glued variables.
Also we discussed that if you´re doing a bunch of HTML code it's
considerably faster to do:
tr
td?= $data ?/td
/tr
Than
print
\n\ttr
\n\t\ttd$data/td
\n\t/tr;
or
print '
tr
td'.$data.'/td
/tr';
I remember benchmark testing it afterwards back then and there was
clearly a difference.

I would tend to agree here; the concat is faster but you may well only
notice in very tight loops. The curly brace syntax can increase code
readability, depending on the complexity of the expression. I use
them both depending on the situation.
Remember the rules of optimization:
1) Don't.
2) (Advanced users only): Optimize later.
Write code so that it's readable, and then once it's working, identify
the bottlenecks and optimize where needed. If you understand code
analysis and big-O etc then you will start to automatically write
mostly-optimized code anyway and in general, I doubt that you'll often
identify the use of double quotes as a bottleneck--it almost always
turns out that other operations and code structures are far more
expensive and impact code speed much more.
That said, you don't really lose anything by using concatenation from
the start, except perhaps some legibility, so as Nathan said it often
really just comes down to personal preference and perhaps the house
coding conventions.

Question is wrt to including a config file on an external server in a

Lets say that on 127.0.0.1 I have test.php with

$obj = new RemoteClass()
do stuff
and on server 200.200.1.1 I have my Config.php file which is contains
the class RemoteClass() { echo test }
If I try to test it locally it says it cannot find RemoteClass ...
How can I include/require a config (or any other php classes file) on
my local running php script ?
As others have said, you are receiving the output of the config.php
after it has been parsed by PHP on the remote server. You could try
naming it config.cfg, config.conf, config.ini, config.inc, etc...
multiple choice
- why not use PHAR
- on remote server enable .phps (php source)
- remove SetHandler application/x-httpd-php in you apache conf (if on
apache, and obviously realise this won't let any php scripts run through
http)
- mount the remote file system locally
and.. why? normal approach would be to expose the remote functionality
needed as a web service and call it via SOAP/RPC/REST etc
however.. always fancied the idea of a central server for php libs that
can be included at runtime (with some local cache'ing and version
checking) - would make most sense if we all used a single version of the
same libs only one copy etc etc

Hi everybody,
i'm trying to apply a method to an object getting its name from a variable,
that i obtain parsing an XML file.
For example:
$object = new Class;
$method = row(); #I'm getting this from the XML parser
$object-$method; #I've an error here...
Obviously the method inside the class exists.
How can i do it?
Thanks a lot in advance.

Use call_user_func() and call_user_func_array() with the callback format:
array($instance, 'method'); for instance methods or
array('class_name', 'method'); for static methods
so you'd want:
$obj = new Class();
$method = row;
call_user_func(array($obj, $method));

Thanks a lot in advance. Your problem is the inclusion of parameters in the $method. You can do the following: ?php $object = new Class; $method = 'row'; $ret = $object-$method(); ? Or if you insist on embedded parameters (but this is a security risk): ?php $object = new Class; $method = 'row()'; $ret = eval( return \$object-$method; ); ?

In your example, I would name my form inputs similar to name
=data[user_id].
Then you just pass the $_POST['data'] array to your function.

You raise some good points. I always name my input fields after the

I suppose I am still in the phase of learning efficiency,
and perhaps
trying to 'get out it' by writing functions that I can just call and
pass parameters instead of fully learning the core concepts.
I just think functions are so damn cool :)
I'll echo what the others have said about the
parameters. For me
personally, if I am passing more than three parameters
(sometimes even
three) I rethink my function. I'm not sure what you envision
using this
function for, but the approach I use for forms and
databases is always
arrays. I get an array from my forms, I insert that
array into the
database, and of course I fetch arrays out of the
database. These are
all indexed the same with the index as the field name
of the table so
it's easy.

There are pro's and cons to this type of thing. In general that is how I do
it too, but you have to be aware of security and organization. It's not
always smart to expose your DB field names directly so you might want to
obscure them for some critical values. If your passing from one controlled
function/method to another then this isnt an issue so much.
I also follow the ruby/rails ideal where tables are plural names (users)
and classes are singular names (user.class.php). Tables always have fields
for 'id','created_on','timestamp','enabled'. Except in 'glue table' cases
(1:n or n:m). Classes extend a base class which handles a lot of the minutea
including the magic __get() and __set() routines as well as knowing what
table they should be through introspection (ie. Their own file name).
No need to name your fields as arrays. $_POST is already an array. You've
just added more complexity/dimensions. When you submit your form just pass
$_POST to your function instead. In the function, is where you should do any
normalizing, scrubbing and unsetting (as per good MVC ideology)...
In your page form:
if ($_POST['submit'] == 'Update')
{
$result = process_data($_POST);
}
Then in some include file somewhere (here is a simplified example of
course):
function process_data($data)
{
//perhaps you don't care about the submit button
unset($data['submit']);
//maybe you don't want everyone to know your DB schema
//so you re-map from form element names to DB fields...
$data['user_id'] = $data['uid'];
unset($data['uid']);
//strip white space off
foreach ($data as $k = $v) $data[$k] = trim($v);
//do validity checking of each important data item
if (intval($data['user_id']) 1) return false;
//any other pre-processing
//do interesting stuff here with scrubbed $data array now
sql_query('UPDATE mytable SET .. WHERE user_id = '.$data['user_id'].'
LIMIT 1');
//of course, I would use a routine that builds the update / insert
statements from
//the array key/value pairs -- see previous attached example
base.class.php in this thread.
